Yebes

The Yebes radio observatory (operated by the IGN Osservatorio Astronómico Nacional) operates 2 radio telescopes, one with an antenna diameter of 40m and another with 13.2m. The 40m antenna can operate in frequency bands 1- 116 GHz and is used for Very Long Baseline Interferometry (VLBI) and single dish observations. The 14m telescope operates in the S and X bands and participates in the Project RAEGE as part of the developments underway for a VLBI Geodetic Observing System, VGOS.
